Sicily By Car – Non-returns of the car rental deposit

On June 19th I rented a car through Booking from Sicily By Car, on the occasion of which I paid a rental deposit. When I arrived at the Sicily By Car headquarters, I was asked to pay again, explaining to me that what I paid before was a deposit that would be returned to me on July 20th. From July 20th until today, the amount of 449 euros has not been refunded to me, although I have made all possible efforts. So BEWARE! when renting cars on Booking for Sicily By Car!
